(PhysOrg.com) -- Physicists have investigated the purest graphene to date, and have found that the material possesses unprecedented high electronic quality. The discovery has raised the bar for this relatively ...

In a new study, published in Science May 31, 2013, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its ...

Ever since graphene was discovered in 2004, this one-atom thick, super strong, carbon-based electrical conductor has been billed as a "wonder material" that some physicists think could one day replace silicon ...

Graphene, which is composed of a one-atom-thick layer of carbon atoms in a honeycomb-like lattice (like atomic-scale chicken wire), is the world's thinnest material  and one of the hardest and strongest. Indeed, the ...

(PhysOrg.com) -- A class of decorative, flower-like defects in the nanomaterial graphene could have potentially important effects on the material's already unique electrical and mechanical properties, according ...

Since its discovery, graphene -- an unusual and versatile substance composed of a single-layer crystal lattice of carbon atoms—has caused much excitement in the scientific community. Now, Nongjian(NJ) Tao, ...

(PhysOrg.com) -- Can graphene -- a newly discovered form of pure carbon that may one day replace the silicon in computers, televisions, mobile phones and other common electronic devices -- be made to bend, ...

Electrons moving in graphene behave in an unusual way, as demonstrated by 2010 Nobel Prize laureates for physics Andre Geim and Konstantin Novoselov, who performed transport experiments on this one-carbon-atom-thick material. ...

Imagine a tablet device as thin as a piece of paper, folded conveniently in your pocket. Or a 3D TV that wraps around the walls of an entire room in your home. With applications that are nothing short of ...

A new breed of ultra thin super-material has the potential to cause a technological revolution. "Artificial graphene" should lead to faster, smaller and lighter electronic and optical devices of all kinds, ...

(PhysOrg.com) -- A team of researchers from Columbia Engineering, the Italian National Research Council, Princeton University, University of Missouri, and University of Nijmegen (Netherlands) has developed an artificial semiconductor ...
